A closed port means that there are no processes listening on that port, which is what the administrator wants to ensure. If the port were in an open state, it would indicate that there is a process actively listening on that port, which could potentially be a security risk. The other choices (open address and closed address) refer to whether a particular IP address is reachable, which is not relevant to the question of whether a process is listening on a particular port.
